Simultaneously Improving Lignin Dispersion and Interfacial Interaction in Rubber/Lignin Composites by Using Deep Eutectic Solvent as a Highly Effective Modifier

ACS Sustainable Chemistry & Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

Lignin, the most abundant aromatic biomaterial on Earth, is widely available as a byproduct of papermaking and biorefinery industries could serve green filler for rubber. However, preparing high-performance multifunctional rubber/lignin composites remains challenging due to inhomogeneous dispersion lignin in rubber matrix poor lignin–rubber interfacial adhesion. In this article, facile modification approach was proposed. Namely, we used deep eutectic solvent (DES), composed choline chloride ZnCl2, simultaneously improve enhance rubber–lignin interaction by constructing metal–ligand coordination bonds at interface. The resulting elastomer exhibited significantly enhanced mechanical oil-resistance properties. Moreover, introduction DES photothermal effect composite. This scalable environmentally friendly strategy anticipated provide novel inspiration large-scale utilization elastomers.

Point‐surface structured modified graphene oxide‐based rubber composites with simultaneous enhanced mechanical properties, low heat build‐up and thermal conductivity

Polymer Composites, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 27, 2025

Abstract Graphene oxide (GO) has been widely applied in the rubber industry due to its excellent insulating and physical properties. However, dispersion always a key factor limiting enhancement of overall performance. In this study, tetrapropoxysilane (TPOS) was used modify GO, creating point‐surface structure. This process resulted SiO 2 @GO, which subsequently employed as reinforcing fillers for preparation composites. The results indicated that structure @GO increased spacing between GO layers effective contact area with matrix, endowing it dispersion. Compared GO/natural (NR) composites, @GO/NR composites exhibited reduced heat generation while demonstrating enhanced mechanical properties thermal conductivity filler content only 0.5 phr. Specifically, value, conductivity, tensile strength, tear strength were 20.7°C, 0.28 W/m K −1 , 28.14 MPa, 108.43 N/mm, respectively. method provided new insights into GO‐based long‐lasting green tires. Highlights had effectively rubber. Rubber showed

Qualification of the Vitrimeric Matrices in Industrial-Scale Wet Filament Winding Processes for Type-4 Pressure Vessels

Polymers, Journal Year: 2025, Volume and Issue: 17(9), P. 1146 - 1146

Published: April 23, 2025

The production of fibre-reinforced composites for use in applications such as type-4 pressure vessels hydrogen storage is achieved through the a thermoset matrix. However, recycling thermosets presents significant challenge due to lack established methods. Epoxy-based vitrimers show characteristics during manufacturing and utilisation phases but exhibit thermoplastic behaviour at elevated temperatures 190 °C. This study investigates industrial-scale carbon fibre reinforced via wet filament winding, exemplified by vessel demonstrator. Processing conditions industrial processes have yet be applied vitrimers; therefore, two vitrimer formulations are compared conventional epoxy thermoset. processability resulting composite quality wound using these materials matrices compared. mechanical properties an interlaminar shear strength test, demonstrating that vitrimeric 19.8% (23 °C) 49.2% (140 improved strength. Consequently, epoxy-based investigated this can employed direct replacement matrix applications, with potential composite. To increase qualities, winding process must adapted vitrimers, since pore free could not achieved.

Towards a global sustainable future and circular economy, the utilization of renewable high-performing biomass-derived fillers for rubber industry is highly desirable but challenging. Carbon black (CB), produced by incomplete combustion or thermal decomposition petroleum hydrocarbons, most dominant reinforcing filler, followed mineral fillers. However, manufacture CB has considerable carbon footprint due to its fossil-based resources; have higher density are generally incompatible with rubbers. It important find abundant, sustainable, cost-effective as substitutes petroleum- coal-derived Biomass-derived fillers, such cellulose nanocrystals, lignin, polysaccharides, biochar, rice husk silica, been extensively explored substitute This chapter provides comprehensive review their applications in industry.
